[PATCH 1/6] staging: r8188eu: remove _dbg_dump_tx_info function

[Phillip Potter]

Remove _dbg_dump_tx_info from hal/rtl8188e_xmit.c as it is just a
dumping function that contains a lot of unclear DBG_88E calls, and has
no other external effect, other than calling a function that ultimately
determines whether or not to dump/trigger the DBG_88E calls. Also remove
its declaration and single call site.

[PATCH 2/6] staging: r8188eu: remove unused function dump_txrpt_ccx_88e

[Phillip Potter]

Remove unused function dump_txrpt_ccx_88e from hal/rtl8188e_xmit.c and
remove its declaration in include/rtl8188e_xmit.h, as this function is
not called from anywhere, and is thus dead code.

[PATCH 3/6] staging: r8188eu: remove txrpt_ccx_sw_88e and txrpt_ccx_qtime_88e macros

[Phillip Potter]

Remove txrpt_ccx_sw_88e and txrpt_ccx_qtime_88e macro definitions from
include/rtl8188e_xmit.h, as these were only called from the now removed
dump_txrpt_ccx_88e function, which was itself not called from anywhere
anyway.

[PATCH 4/6] staging: r8188eu: remove empty function rtl8188eu_free_xmit_priv

[Phillip Potter]

Remove empty function rtl8188eu_free_xmit_priv from hal/rtl8188eu_xmit.c
and its declaration from include/rtl8188e_xmit.h, as well as the one
place where it is stored in the free_xmit_priv function pointer of the
HalFunc struct inside padapter. This is safe, as the wrapper function
checks for NULL before calling this function via the function pointer.

[PATCH 5/6] staging: r8188eu: remove function rtw_hal_free_xmit_priv

[Phillip Potter]

Remove function rtw_hal_free_xmit_priv in hal/hal_intf.c and its
declaration in include/hal_intf.h, as well as the single call line in
core/rtw_xmit.c. This function now essentially checks a function
pointer which will always be NULL (due to previous patches) and
therefore will never be called.

This entry could have been removed in patch 4/6 or 5/6, but I guess 
it's okay to do that here as well. Perhaps the three patches from 4/6 
to 6/6 could have been merged into one (because since 4/6 was 
immediately clear that this operation has no use at all).

Aside from the above considerations, it looks good. So...
